Application filed February 14, 1919.. Serial in 277,089. 1

To all whom it may concern:

Be it known that I, JAMEs H. OAPLAN, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Bufling Covers for R0- tary Brushes, of which the following is a specification. a

The object of the invention is to provide a more durable and efiicient rotary brush cover used for bufing purposes and a simple and inexpensivemethod of making up the same.

In order to illustrate my'invention I have shown in the accompanying drawing a single embodiment thereof, wherein Fig. 1 is a perspective view of a coverof my invention shown applied to an ordinary rotary bufiing brush of the. broom straw type,

Fig. 2 shows the cover set as shown in Fig. 1 but with the cover removed;

Fig. 3 is a sectional view taken on lin 3-3 on Fig. 1, but shows the brush in elevation and not in section.

Fig. 4 is an enlarged perspective viewof the cover.

Fig. 5 shows the development of the circular cover as laid out diagonally on the fabric from which the same is made, so that the texture of the finished cover comes on the bias and not on the straight weave of the fabric.

Fig, 6 shows a diagrammatic view of a buffer-cover in action with a shoe being treated thereby. p

The terms employed herein are used in the generic and descriptive sense to designate parts or elements, and are therefore not intended primarily as terms of limitation.

In the drawing, the numeral 10 represents a closed, circular brush cover member of my design which is cut from the fabric or material m (preferably known as drill fabric) diagonally across the run of the same, as shown by the strip B in Fig. 5, for the purpose of eliminating the straight weave of the fabric running circumferentially around the finished brush cover, as is invariably the case -with the usual brush covers in use today for bufiing purposes.

11 represents the cover joint which is made diagonal, as shown in Fig. 4, where,

' the free ends 12 and 13 of the cover (which are cut diagonal and parallel) are permanently joined, as shown by the stitching S Specification ofLetters Patent, I

. or by any other suitable manner, for affeot r:

ing an endlessbelt feature to yield the closed and circular effect required for the cover. The side edges 14 and 15 areeach-folded baokand secured to the cover, as by the stitching 16, to form drawstring grooves;

or channels around the sameswhich are open at the joint as O? through which the drawstrings, cords or, tapes F D may be drawn and protrude for thepurpose of securing the cover in operating position. with they brush, as shown in Fig.1. 1'? represents an ordinary rotary buffing brush whichis-used more partlcularlyin the shoe manufactur ing business; 18, represents the brush bristles which are usually ,of. the broom straw type i set radially in the brush','as'shown in Fig. 1.

f -:Having thus dSQl'ibed .themethodpf; making and vthe details of my invention, the

is as follows ff manner in which. the same may beemployed I The drawstring's D. are loosened and freed so that the sides of the-cover may be full open, as shown dotted in Fig. 3, whereupon the same may be slipped over the bristles of the brush 17 into the position there shown dotted, thenthe overlapping sides may be folded over the brush by the tight- 1 ening up on the drawstrings which effects a gathering feature to the sides of the cover,

r as shown in Figs. 1, 2 and 3, then with the drawstrlngs properly tied up to keepthe' cover in such positionthe same becomes ready for working operation, it being understood that a cover so fitted and secured to the brush with which the same is assooif ated will be causedv to rotate with the brush and may then serve as a buffing wheel,

While buffing covers have been used here-' tofore in the shoe making business, yet it is a faot that the same have always been cut the straight way of the fabric and not onthe bias, as is true of my invention; .and

further, where closed covers (meaning unit endless covers) were used, the same were not only cut on the straight weave of the fabric but the joint was made straight across and parallel with the axis of the wheel and not oblique and diagonal to'it as my invention calls for.

By making the cover with the weave and rather than on thestraight of the fabric,

the life of the cover is greatly: increased since the resistance upon it is greatly decreased, for the friction and wearof theobject being treated thereagainst is no longer 7 localized, as is the case with the straight out working section of the cover against the strain encountered" thereby. 10'

It must be understood that the oblique positions of the warp and filling threads of the fabric'serve better binders for the 1 bristles of the brush than can be had with the filler threads positioned parallel with the brush axis; and that the oblique positions of the threads of the fabric allow for a greater supporting feature thereto over a longer length of brush than is otherwise attainable. Therefore, the cover becomes better qualified to resist the work and friction against it and becomes more durable and lasting.

Having thus described my invention in detail, what I claim as new is:' a

1. A circular buffer brushcover compris- V inga strip of fabric cut on the bias with'the f endsthereot cut parallel to each other but buffer brush.

to form drawstring channels; and draw- 1 strlngs provided in said channels for secure ing the cover 2. A closed circular buffer brush cover comprising a strip of suitable fabric cut on the bias having parallel ends diagonally disposed to the'sides of said. strip andpermanently secured together to' form a complete circular band of said strip, drawstring retaining means provided on the sidesof said brush'cover and provided with drawstring outlets at the joint section of said cover, and drawstrings adapted to gather the sides of the cover for securing the same to thebuiier brush. v v

In testimony whereof, I hereunto set my hand'this twelfth day of February 1919.
